My invention relates to side frames for car trucks and has as itsprincipal object the provision of an improved side frame of the integraljournal box type which shall possess the characteristics of increasedstrength and durability combined with economy of manufacture.

The novel features of my invention are pointed out with particularity inthe appended claims. The invention itself, however, with further objectsand advantages, will best be understood from thefollowing descriptiontaken in connection with the accompanying drawing in which:

Figure 1 is a top plan view of a side frame according to my invention;

Fig. 2 is an elevational view of the side frame illustrated in Fig. 1,part being broken y;

Fig. 3 is a transverse sectional view of the frame shown in Figs. 1 and2, taken on the line 33 of Fig. 1;

Fig. 4 is a section on the line 4-4 of Fig. 2;

Fig. 5 is a section on the line 5-5 of Fig. 2

Fig. 6 is a section on the line 66 of Fig. 2;

Fig. 7 is a section on the line 77 of Fig. 2;

Fig. 8 is a section on the line 8-8 of Fig. 2;

Fig. 9 is a section on the line 99 of Fig. 2:

Fig. 10 is a section on the line 10-10 of Fig. 2.

Theside frame illustrated in Figs. 1 to 10 inclusive compriseslongitudinally extending top and bottom members or chords 1 and 2respectively. and two columns or struts, such as 4, extending betweenmembers 1 and 2. The top member 1 is connected to the bottom member 2 atpoints near the ends of the frame. Struts 4 divide the space betweenmembers 1 and 2 into three apertures, the central one of which isroughly quadrilateral, and the other two of which arerou'ghlytriangular. The members 1 and 2 are channel shaped or U-shaped .in crosssection throughout most of their lengths, the central webs of thesemembers being on top in the case of member 1 and at the bottom in thecase of member 2. Struts 4 are integral with members 1 and 2 and arealso channel-shaped or U-shaped in cross section,the central plates orweb of these struts being on the sides toward the said central aperture.

I provide outwardly-extending beads, such as 5, around the edges of saidtriangular apertures, said beads being widened outwardly in sectors nearthe lower ends of struts 4 to. form flanges such as 6. Theoutwardly-extending flanges 6 serve to reinforce the frame at the anglesformed between struts 4 and chord 2.

Between the struts 4, the chord 2 has an upper central or horizontal web8, and in this sector the chord 2 has also outstanding flanges, such as9, at each side thereof in the same planeas web 8, forming therewith aspring seat 10 in which is an aperture 11 for interlocking the springplank, not shown, with the side frame. Itis evident that in the sectorbetween the struts 4, except at aperture 11, chord 2 is of box section.

The top member 1 extends somewhat beyond the points of junction betweenitself and the. bottom member 2, and in the angle thus formed I providejournal boxes, such as 12, which are integral with members 1 and 2, thecentral webs of chords 2 merging into the side walls of the boxes asillustrated in Fig. 4. The top member 1 extends across the tops of thejournal boxes 12, the depending flanges of member 1 being integral withthe tops of the boxes. Member 1 is preferably open at both ends asappears at'13 to permit the ready removal of cores. j

The brake beam hanger brackets 14 are also preferably integral with theframe. extending rearwardly, at the upper angles of the said triangularapertures near the upper ends of struts 4. l

While I have shown and described a side frame of specific outline, I donot wish to be limited to this. i

It will be seen that a s de frame according to my invention in which thechord and column members are of U-section and the chord members integralwith the journal boxes is of great strength, especially when the upperchord member extends over the tops of the journal boxes, thus forming anintegral box section therewith. It will be seen alsothat the projectingflanges 6 increase the strength of the entire frame without materiallyincreasing its weight, while'the box section at the spring seat alsoreinforces the entire structure.

Having thus described my invention, I claim:

1. An integral metallic car truck side frame of truss form comprisingtop and bottom chords of U section, spaced columns defining a centralbolster receiving opening, and journal boxes having their top, bottomand side walls integrally formed, said top chord having spaced sideflanges extending downwardly from its web, said journal boxes beingdisposed beneath the ends of the top chordand having their top wallsbeneath the web and integral with the overlying spaced depending flangesof the top chord to form, with the side flanges and web of the topchord, a rigid boxlike structure extending substantially the full widthof each journal box, said bottom chord having end portions inclinedupwardly toward the top chord and integra ly joined to the side flangesof the top chord adjacent the top inner corners of the journal boxes,the s de flanges and web of the bottom chord merging into the inner sideWalls of the journal boxes at and below the upper inner' corner thereof,whereby the integrally formed journal boxes are positioned in the anglesbetween the ends of the topand bottom chords and the entire structure ofI each ournal box lends a resistance to the tensional forces acting uponthe bottom chord.

2. An integral metallic car truck side frame of truss form comprisingtop and bottom chords of U sect on, spaced columns defining a central boster receiving opening, and j ournal boxes having their top, bottom andside walls integrally formed, said top chord having spaced side flan gesextending downwardly from its web. said journal boxes being disposedbeneath the ends of the top chord and having their top Walls beneath theweb and integral with the overlying spaced depending flanges of the topchord to form. with'the side flanges and web of the top chord. a rigidboxlike structure extending substantially thefull width of each journabox, said bottom chord having end portions inclined upwardly toward thetop chord andhaving its spaced side flanges merging into the s deflanges of the top chord inwardly of the journal boxes and its spacedside flanges and web merging into the inner side walls'of the journalboxes at and below the upper corners thereof, whereby the integrallyformed journal boxes are positioned in the angles between the ends ofthe top and bottom chords and the ent re structure of each journal boxlends a resistance to the tensional'forces acting upon the bottom chord.

In testimony whereof I afiix my signature.
